[Lowfer] Operating from 12VDC battery full time.

Sun, 24 Feb 2002 14:04:07 -0600

Well, I would go with a killer 60 and 120hz notch filter and then a big hash
choke and a big electrolytic cap on the line as well. I used to use a 1F
(farad) cap in my car audio system and it really kept the DC line smooth and
noise free. How about one of those high current noise filter boxes that Rat
Shack sells??? I think it is cheep enough to try.

I ran lowfer beacon 1LF on solar panels for quite some time, and it worked
well...but I suspect that with a nearly 1 Amp current drain during
receive the Icom will run down a battery quickly unless I used
a massive solar array. For maximum frequency stability, I leave
the Icom on 24/7. I'd estimate that I transmit less than 5 minutes
per day on average and often miss several days without transmitting
at all.

Is there a way to filter the charger's input so that I don't pick up more
noise from it? Someone mentioned putting  a choke on the charger but
no details.

Any and all help appreciated.
